You need a Signed-off-by: Zhang Qing <zhangqing@...k-chips.com>

I think Lee's "Grim" comment here was that prefixing globals with "g_"
is not consistent with the Linux coding style.  Just remove the "g_".

nit: with {} we have space, so:

{ RK808_BUCK3_CONFIG_REG, BUCK_ILMIN_MASK,  BUCK_ILMIN_150MA },

instead of:

{RK808_BUCK3_CONFIG_REG, BUCK_ILMIN_MASK,  BUCK_ILMIN_150MA},

nit: add spacing so that VB_LO_SEL_3500MV lines up under VB_LO_ACT
